The Opportunity

At Lumber, you’re not just pushing pixels—you’re shaping how thousands of construction teams experience technology in the field and on the jobsite. This is a chance to build UI that doesn’t just look good, but actively solves real-world problems for workers who don’t have time for clunky apps or slow interfaces. You’ll join a high-ownership, fast-moving engineering team where your decisions directly influence product direction and user experience. This role gives you the chance to design and ship polished, high-performance interfaces end-to-end, while working closely with product and design to solve real-world problems at scale.

What You’ll Do

• Develop, optimize, and maintain highly interactive, user-friendly web applications.
• Collaborate with product designers and backend engineers to translate UI/UX wireframes into responsive, high-quality code.
• Own features end-to-end: from technical design, development, testing, deployment, and monitoring.
• Ensure performance, scalability, and cross-browser/device compatibility of applications.
• Write clean, maintainable, and reusable code following best practices.
• Contribute to design discussions and architectural decisions for frontend solutions.
• Debug, troubleshoot, and resolve production issues in a timely manner.
• Stay updated with the latest trends and advancements in frontend technologies.

What We’re Looking For

• Core Expertise:
  
  • Strong proficiency in JavaScript, Typescript, ES6+ and React.js, React native (with hooks, context, state management like Redux/Zustand, etc.).
  • Solid understanding of HTML5, CSS3, and modern frontend tooling (Webpack, Babel, Vite).
  • Hands-on experience with UI frameworks/libraries (Material UI, Tailwind CSS, Chakra UI, etc.).
• Familiarity with RESTful APIs, GraphQL, and integration with backend services.
• Understanding of software development best practices, Git workflows, and CI/CD pipelines.
• Excellent problem-solving, analytical, and communication skills.
• Ability to thrive in a fast-paced, high-ownership, collaborative environment
